How the Korean War derailed China’s plans to attack Taiwan

Why the Taiwan attack stalled

The article finds that the plans for a 1950 attack on Taiwan were constrained above all by the Chinese Communist Party’s lack of sufficient naval and air power. The party expected Soviet help to build those capabilities and possibly assist an attack, but Stalin redirected the Soviet Union’s approach: he stopped indirect assistance for the Taiwan operation while giving Kim Il Sung the go-ahead to attack South Korea.

The study argues that this decision, rather than the Korean War’s outbreak alone, is central to understanding why the Taiwan plans were shelved indefinitely. Once the Korean War began, and after the Sino-Soviet alliance treaty was signed, the United States changed its policy toward Taiwan, helping turn the issue into an international confrontation.

How Taiwan became international

The findings revise a simple account in which the Korean War and the arrival of the US Seventh Fleet merely interrupted an otherwise feasible Chinese attack. They place the Soviet Union’s alliance strategy at the center of the story: the same relationship that China needed for military preparations also contributed to the abandonment of those plans and to the internationalization of Taiwan’s status.

Records and limits

The article is a historical analysis based on archival materials from the Republic of China, the People’s Republic of China, the United States and the former Soviet Union, along with other historical documents. Its conclusions come from reconstructing decisions and policy changes across these governments, rather than from an experiment or a quantitative comparison. The evidence supports the article’s interpretation of the sequence and motives, but archival records cannot directly test every possible explanation for why the attack plans were delayed or abandoned.
